Trace information generation apparatus for generating branch trace information omitting at least part of branch source information and branch destination information on target processing

摘要

A branch trace information generation unit generates branch trace information omitting at least part of branch source information and branch destination information on a target processing based on instruction execution information showing an instruction execution status of an instruction execution unit. A trace information output unit generates and outputs trace information capable of restoring an instruction executed by the instruction execution unit from the branch trace information generated by the branch trace information generation unit. It is, therefore, possible to reduce data amount of trace information.
